It doesn't end there, though. New Eagles safety Malcom Jenkins said he thought Giants quarterback Eli Manning's best days "might be behind him."

While the Eagles are expected to repeat as division champions, head coach Chip Kelly might want to remind his players they did not clinch the title last season until the final two minutes of the season -- despite a down year from the Giants and the Washington Redskins, and despite facing a Tony-Romo-less Dallas Cowboys team in Week 17.

So while it is good to be confident, the Eagles might be reaching the point where they have to hope the jabs they keep throwing at the Giants don't come back to bite them
